Combat support agency

DoD Organization December 2013

Combat Support Agency (CSA) is a designation used within the United States Department of Defense (DoD) to identify agencies that provide military support beyond the standard force structure. These agencies play a crucial role in supporting the armed forces with specialized services, intelligence, logistics, and capabilities that are essential for operational effectiveness and efficiency across a wide range of military operations.

Overview

Combat Support Agencies are distinct from combat units, which are directly involved in the execution of military operations. Instead, CSAs offer support that enhances the combat readiness and operational capabilities of the combat forces. This support can include, but is not limited to, intelligence gathering, cybersecurity, logistics, communications, and research and development. The designation of an agency as a CSA is determined by the Secretary of Defense and is based on the agency's mission, capabilities, and the critical support it provides to combat forces.
